To @Zt whom t may conoci/'71,:

Be it known that I, JACOB M. RHODES, re-

siding at Fredericktown, in the county of Madison and State of Missouri,have invented a new and useful Combined Vibrating Harrow and Roller, ofwhich the following is a specication.

My invention relates to agricultural implements, and more particularlyto that class of implements known as combined harrows and rollers, theobject of the invention being to provide an improved implement of thisclass of simple, economical, and durable construction, which in oncepassing over the ground will pulverize the soil, out all small roots fora certain depth in the ground, pulverize the soil, and smoothly roll it.With this object in view my invention con*- sists in the improvedconstruction, arrangement, and combination of parts hereinafterdescribed and afterward specifically pointed out in the appended claims.

In order to enable others skilled in the art to which my invention mostnearly appertains to make and use the same, I will now p roceed todescribe its construction and operation, reference being had to theaccompanying drawings, forming part hereof, in which-y Figure 1 is a topplan view of an improved implement constructed in accordance with myinvention. Fig. 2 is a vertical longitudinal sectional view on the planeindicated by the dotted line 2 2 of Fig. 1, the central beam of theframe being partly broken away. Fig.

3 is a detail sectional view on the dotted line 3 3 of Fig. 1. Figs. 4and 5 are respectively side and front elevations of one of the knives orroot-cutting teeth.

Like numerals of reference markA the same parts wherever they occur inthe various iigures of the drawings.

Referring to the drawings by numerals, 7 indicates a centrallongitudinal top beam secured upon a rectangular wooden frame comprisingfront beam 8, rear beam 9, and side beams 10 and 11, to which frame allthe working parts are attached.

12 and 13 indicate two sections of a harrowframe pivotally secured tothe lower ends of links 14 and 16 and intermediate links pivotallyconnected at their upper ends to the side 'beams 10 and 11 andcentral'beam 7, the two sections 12 and 13 being also hinged together ontheir central longitudinal sides, as at 17. To oneof the inner side barsof one of the sections of the barrow-frame is pivoted a link 18, whichat its opposite'end is connected pivotl ally to the lower end of a hand-lever 19,-v

which passes through a curved rack 2O and a slot 2l in the beam 7 and ispivoted at the center of the rack at 22. One-half of the teeth of thecurved rack are omitted, as shown at 23. Above the rack a pawl 24 isslidably mounted on the hand-lever 19, which is connected by a wire bail25 to the small arm 26 of an elbow-lever pivoted at 27 to the handlever,the longer arm 2S thereof extending upward in close proximity to thehand-lever and normally held away from the lever bya spring 29. At thepoint 30, a short distance from the pawl, the hand-lever is connected tothe beam 7 by a spiral spring 31, arranged to normally maintain the pawl24 upon the blank portion of the curved rack, but to permit the lever,and consequently the barrow-frame, to vibrate longitudinally on its supporting-links 14 and 16.

The barrow-frame sections are each provided with an uneven number(preferably live) of cross-bars, the first, third, and fifth bars(marked 32) being provided with ordinary harrowteeth 33, and the secondand fourth bars (marked 34) with knife-teeth 35, the latter being shapedas shown in Figs. 4 and 5, being triangular in cross-section, with anacute angle to the front, forming a cutting edge 36, which iscurved-inward from top and bottom, as at 3738, the sides also beingcurved inward, as at 39 40.

An ordinary harvester-seat 41 is mounted on beam 7 in the rear of thecurved rack to render the hand-lever readily accessible to IOO areconnected to the tongue by coupling-bolt 50 in the usual manner.

In the rear portion of the frame two rollers 51 are journaled on asingle shaft 52, said rollers being composed of wooden staves 53, heldby end wheels 54, of metal, flush with the outer surface of the staves.A scraper 55 bears upon the rear surfaces of the rollers and serves toclear off clay or other matter which sticks to them.

The foregoing` will give a clear understanding of the construction ofthe invention, and its operation may be described as follows: Theimplement having been brought to the eld to be worked, the hand-lever isadjusted to the position indicated in Fig. 2, the tongue having beenproperlyelevated by the means before described, and the team is started.The ordinary harrow-teeth 33 pulverize the soil in the usual manner,while the knifeteeth cut small :roots below the surface and the rollerssmooth the surface and mash any clods which the harrow may pass over,said rollers being kept clear and clean by the scraper. During theoperation the harrow will vibrate forward and backward on itssupporting-links, the spring 3l permitting it to give or yield backwardwhen extra obstructions are encountered and forcing it forward to itsnormal position when such obstructions are passed. Vhen turning, ifdesired, or when it is desired for any purpose to raise the harrow, thelever 19 is drawn forward, the pawl 24 being rst raised by means of theelbowlever, which movement of the hand-lever will swing the harrowbackward on links 14 15 16, raising it off the ground, where it may beheld as long as desired by releasing the elbow-lever and permitting thepawl to engage the teeth of the curved rack.

WhileI have illustrated and described what I consider to be the bestmeans now known to me for carrying out my invention, I do not wish to beunderstood as restricting myself to the exact forms and constructionsshown, as many slight changes therein or variations therefrom mightsuggest themselves to the ordinary mechanic, all of which would beclearly included within the limit and scope of my invention.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

1. The combination with the implementframe, of the harrow, thelinks`suspending the harrow, the hand-lever pivoted through the frameand connected below it to the harrow, and the spring connecting thehand-lever with the frame, substantially as described.

2. The combination with the implementframe, of the harrow, the linkssuspending the harrow below the frame, the curved rack with part of itsteeth omitted, the hand-lever pivoted in through slot in the frame atthe center of the curved rack, the pawl slidably fixed on the hand-leverabove the rack, operating devices for the pawl, and the springconnecting the hand-lever to the frame, substantially as described.

3. The combination with the implementframe of the yielding vibratoryharrow, supporting spring, and means for locking it against vibration,substantially as described.

il. The combination with the implementframe and the yielding vibratoryharrow, of the hand-lever, the rack-and-pawl mechanism, the rollerjournaled in the frame and the scraper, substantially as described.

5. The combination with the implementframe of the yielding vibratoryharrow provided with alternate rows of ordinary harrowteeth androot-cutting teeth, substantially as described.

6. The combination with the 'implementframe consisting of front, rear,side and central beams, of the harrow in two sections hinged togetherbelow the central beam, links pivotally suspending the barrow-frame fromthe side and central beams, a hollow curved rack mounted over a slot inthe central beam, and having part of its teeth omitted, a handleverprojecting through said slot and pivoted at the center ot' the curvedrack, a sliding pawl on the lever straddlin g the curved rack, and aspring connecting the lever with the central beam, substantially asdescribed.
